F40 Euro tanks..storage

For long term storage (over 6 months) should the bladder tanks be full or dry?

thanks!

 

get VP fuel and then you dont need to worry about it

 

That's interesting - thanks. What's the thinking behind using vp? Additives or something else?

I have normally left mine with half to two-thirds of a tank of ethanol-free regular fuel.

 

normal pump gas goes bad in 6 months, the VP stuff lasts a few years

 

So the bladder tanks prefer to stay wet ?

 

The OEM advice is to keep them wet. This is another reason why it is preferable to have recent manufacturing dates when installing new bags.

 

VP makes ethanol-free gas in 5 and 50 gallons. Its the ethanol that eats the rubber.

 

In the UK I normally use BP Ultimate (which is readily available at from the pumps at filling station) and is rated E0 (zero-ethanol), and is only about 10% more expensive than regular 5% ethanol fuel. Unfortunately, the law here will soon mean that the ethanol content will go up to 10% on all fuels at which point we will need to find some VP-equivalent. Thanks for the info.

 

What is VP fuel?!

 

VP produces various racing fuels among them ethanol-free ones
